趣味知識

Ajkaceratops is the first ceratopsian dinosaur ever found in Europe that scientists are sure about.2

Its fossils were discovered in a former floodplain and channel deposit, made of clay, silt, and sandstone.1

The name Ajkaceratops honors the town of Ajka in Hungary, where the fossils were found.1

Ajkaceratops may have lacked the frill and horns that other ceratopsians had.1

Its ancestors probably reached Europe by island-hopping across the Tethys Ocean.2

A 2026 study using a more complete skull confirmed that Ajkaceratops is a true ceratopsian.1
